Air quality today
The air quality in Monte Romano today is classified as Good. The primary pollutant identified is PM10, and the measured concentration aligns with a reference value of 13.0 µg/m³ based on five valid observations recorded by OpenAQ.
Overall conditions meet the criteria for a Good rating according to the latest assessment. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The Monte Romano air‑quality record currently consists of four pollutant measurements drawn from a single monitoring station, giving one row per substance. All values are expressed in micrograms per cubic metre (µg/m³). The most recent data point for nitrogen dioxide (NO₂) was recorded on 2026‑02‑09 at 03:00 UTC, showing a minimum of 1.0 µg/m³, a median of 1.5 µg/m³ and a maximum of 2.0 µg/m³; the 10th and 90th percentiles sit at 1.1 and 1.9 µg/m³ respectively. Carbon monoxide‑related nitrogen oxide (NO) was last updated on 2026‑02‑09 at 00:00 UTC, with every reading equal to 0.0 µg/m³ across the same minimum, median and maximum. The broader NOX metric shares that timestamp and reports a uniform value of 3.0 µg/m³ for all three statistical points (min, med, max). Particulate matter ≤10 µm (PM10) is slightly older, with its latest entry from 2026‑02‑08 at 00:00 UTC, consistently recorded at 13.0 µg/m³.
Because the dataset contains only one row per pollutant, there is no variation in station count over time; all observations are recent, falling within a seven‑day freshness window. However, the uniformity of values for NO, NOX and PM10 (each showing identical min, median and max) indicates that the current sample does not capture any fluctuation for those substances, whereas NO₂ exhibits a modest spread between 1.0 and 2.0 µg/m³. The overall coverage is therefore limited to a single location, meaning conditions elsewhere in Monte Romano may differ from what these figures represent.
